Chairman Gao Jianjun shared in his speech the cooperation process between Baofeng and Shenyang Blower Group in promoting the localization of major equipment. He indicated that Baofeng's air separation compressors have been put into practical application from 105,000 to 110,000 units With its outstanding technical strength stable and reliable equipment quality, and accurate and efficient operation and maintenance services, Shengu Group has laid a solid foundation for the safe, efficient and stable operation of all sets of equipment in Baofeng, and has helped the Baofeng Inner Mongolia project operates at full capacity and safely for over 14,400 hours future, both sides will continue to deepen cooperation, jointly polish the new business card of major national equipment, and continuously contribute more to ensuring national energy security and promoting high-end equipment for the nation.
Huang Li, the president of the China Communications Association, attended the promotion meeting and delivered a speech. She pointed out that the orderly development of deep processing of coal represented by coal-to-liquids, coal-to-gas and coal-to-olefins is an important national energy strategy, which is of great significance for ensuring national energy security and adjusting the energy structure. The leaders and engineering technicians of Shengu Group have made tremendous efforts throughout the entire process of the research and development of "large-scale air-penetrating units". It demonstrates Shenyang Blower Group's comprehensive capabilities and sense of responsibility in undertaking the localization of major national equipment. Subsequently, President Huang Li announced the appraisal results of the morning appraisal meeting.
Zhang Yong, the chief engineer of Shenyang Blower Group, delivered a keynote speech titled "Focusing on Breakthroughs in Key Equipment to Empower the Upgrading of the Air Separation Industry", systematically reviewing the technological evolution of Shenyang Blower Group's large-scale air separation compressors over the past 20-plus years. He highlighted the company's core strength, scenario-based solutions, full life cycle services, and future development directions.
Liu Wanqing, vice president of Shengu Group, presided over the promotion meeting.
Bai Weiwei, the deputy general manager of Inner Mongolia Baofeng Coal-based New Materials Co., LTD., introduced the actual production and operation situation of the unit.
Liu Shangjin, the vice president of Hangzhou Oxygen Group Design Institute, introduced the overall operation of the unit from the perspective of the air separation complete set.
The successful holding of this appraisal meeting and promotion meeting marks that Shenyang Blower Group has achieved a full-chain closed loop from technological breakthroughs to industrial application, from product delivery to industry recognition in the field of compressor units for ultra-large air separation units. It also indicates that China's core equipment for ultra-large air separation has formed a complete and independent technical system and industrialization capabilities. It has the solid confidence to compete on the same stage with the international leading level.
Taking this as a new starting point, Shenyang Blower Group will continue to shoulder the mission of being a "national weight", focus on the continuous iteration of core technologies for high-end equipment, deepen the collaborative innovation among industry, academia, research and application, and accelerate the upgrading of large-scale air separation equipment towards greater efficiency, intelligence and greenness. Shengu will always adhere to the core values of "achieving customer success, focusing on quality, continuous innovation, and pursuing excellence". With more advanced and reliable equipment and more high-quality and considerate services, it will contribute to the high-quality development of the energy and chemical industry, and make new contributions to ensuring national energy security and promoting the localization of major equipment.

Shengu Group's new generation of super-large air separation compressors
The super-large air separation unit compressor unit developed and manufactured by Shengu, as the core power equipment of the ultra-large air separation unit, is mainly applied in the methanol project of the Inner Mongolia Baofeng Green Hydrogen and Coal Chemical Coupling Carbon Reduction Innovation Demonstration Project. It is an indispensable key core equipment of the entire large-scale air separation system. Six sets of units form the largest domestic air separation cluster that is fully domestically produced. This unit is overall divided into an air compressor, a booster, drive equipment and various auxiliary systems. It mainly undertakes core processes such as air intake, multi-stage compression and pressurized transportation, providing sufficient and stable-pressure process compressed air for the entire air separation unit. It is the basic guarantee equipment for the air separation system to achieve air separation and prepare industrial gases. The air compressor adopts the SACC "6+1" axial flow + centrifugal structure: composed of 6 stages of axial flow blades and 1 stage of centrifugal impeller, with axial intake and radial exhaust, and is equipped with primary inter-stage cooling. The booster adopts the SVK63-6H assembled structure, consisting of 6 stages of impellers and equipped with 4 stages of inter-stage cooling. Key indicators such as efficiency, vibration and energy consumption have reached the international advanced level, and some indicators are even better than imported products.
Since being put into commercial operation, the six sets of compressor units have been in continuous and uninterrupted operation for a long time, and have performed well in on-site use. The unit starts and stops smoothly, and the adjustment is flexible. The automatic control system responds quickly, which can meet the high-load and long-cycle production requirements of coal chemical projects. The overall energy consumption control of the unit is excellent. The actual operating energy consumption is lower than the design value, and the vibration and temperature rise indicators have remained stable in the excellent range for a long time. At the same time, the unit has good compatibility with Hangzhou Oxygen's air separation system. The oxygen production capacity of the entire set of equipment is stably maintained at 110,000 nm ³/h of the rated load fully meeting the gas demand of the methanol project and downstream production facilities.
